To all whom it may co'aoerf/L:` i

Be it known that I, CHARLES` W. DANGLE- MEYER, a citizen of the United States, and resident of Dubuque, in the county of Dubuque and Stateof Iowa, have'invented new and useful Improvements in Portable Milling- Machines, of which the following is aspeciicatlon. i i My device relates to rportable millingV ma-V chines with special reference to `such as are used in facing the-jaws of theframesof locomotive engines, where it is. necessary `to change the angle of the machine to face or mill the jaws set at :different angles to the frame of the engine; and the object is to provide a power machine which may be rremovably attached to the frameand jaws of the engine and, withoutremoval therefrom,

be adjusted in such amanner that the cutters.

will mill the face of the jaws .at whatever angle they may be setwith relation to the frame of the engine and make this adjustment accurately and without the aid of an expert mechanic. L Y y The following specification will set out in detail the manner of construction and the mode of operation. when 1 taken` in connec-` tion with the drawings accompanying the same and forming a part hereof. l

Figure 1 is a plan view taken from the front of the device, when attached to the frame of an engine and jaws. Fig.` 2 isl a back view of the device removed from the engine frame.` Fig. 3` is a side4 elevation of the device. Fig. 4 is a longitudinal section of the head together with the shaftV that carries the cutters and its attachments. Fig. 5 is a perspective view of a cross-bar'. Fig. 6 is a perspectiveview of al` detail locking device. Fig. 7 is a perspective view-of an attachment used with Fig. 46. Fig. 8 is a part perspective and part sectional view of the head with the shaft that carries the cutters `and attachments forfeeding the cutters. Fig. 9 is an end view of the device for setting the cutters parallel `with the jaws. Fig.` 10 is across section through line X-X ofFig. 2.

Like characters of reference denotecorresponding parts in each .ofthe figures.

Referring to the drawings 2 designates the frame of the engine, 4 one ofthe jaws set at right angles to the frame and 5 the other jaw set at a different angle. frame 2 is hung a plate 6 by hangers 8 resting upon the frame and rigidly held to the frame 2 by the clamps 10.@ These clamps preferp Upon the top of the.

I ably consist' of a bar. of steel bent at each end,

thus roviding two arms,'one` of the arms of the c ampengages one side of theplate 6, and the other arm extends over'on the op- 60 positeside of the engine frame and is held more rigidly by a screw (not shown) engagingthe engine frame. The plate is provided witha T sha ed or' dove-tailed groove 12, in which theen argedV heads of bolts 14, for adjustably securing the hangers 8 to the plate 6, are adapted to" slide and hold the plate upon the frame in any adjusted position. This is important as the adjustment must be exceedingly accurate and ofttimes the variation of a hundredth part of an inch is fatal to. the facing,-and in order to be quickly adjusted so that the cost of facing shall .be materially reduced over the same work by hand, these accurate adjustments must be vmaole quickly, and by means of the vplate 6 being secured tothe side of the engine frame the Cparallel adjustment is always maintained an the cutters always at right Vangles .tothe jaws ofthe engine frame to be milled, and then by the gages the accuracy of 4the, engine adjustment is perfected and can be accomplished in a few minutes, and without the removalof the engine from the frame.

The millingdevice with the machinery for operating the same is attached to a frame 16, widened at the top and provided with an opening inthe center through which a bolt 20, having its head in the groove 12 of the 90 plate 6, firmly and adjustably holds the frame on the plate. Upon the opposite sides of the bolt 2O in the plate 6 are two oblong holes 22 and 24 in which are bolts 26and 28 with the heads of'said bolts in the groove 12. 95

The lower end of the frame 16 is bolted to a plate orcross-bar 25 to which are adjustably secured hangers 3() by bolts 32 in slots 34 in plate 25. This plate 25 is secured t0 the end of the jaws 4 and 5 by clamps 33 engaging 100 .is bent at 19 and provided with the female 105 `dove-tail 29 which is adapted to slide over the dove-tail 21. It is also secured from any movement by a set screw 36 passing through the plate 25 into a block 31 1n the dove-tail and in this manner it is securely held and can .110 `be adjusted by the set screw 36.

Ahead 40 with a dove-tail 42 corresponding to the dovetail of the plate 25 engages the dove-tail 21 in the frame 16 and slides thereon. In one side of the head 40 is secured a block 44 provided with a screw threaded opening 45, through which a screw 46, subsequently to be described, engages and operates to raise and lower the head. The head also consists of a sleeve 48 through which runs a shaft 50 which carries the cutters 52 and 54. Around the outer end of the head is a collar 55 which is screwed upon the head. The outer end of this collar is screw threaded and upon it is screwed a cap 56. One end of the shaft 50 is 'provided with a shoulder 58 and the collar 55 is provided with a shoulder 60 and by means of the collar 55 with its shoulder 60 contacting with the shoulder 58 on the shaft 50 and the cap 56 also contacting with the shoulder 58, the endwise adjustment of the shaft 50 and cutters carried thereon is accomplished. The other end of the sleeve is a worm gear; this gear may be a part of the sleeve or keyed on the sleeve. In the shaft 50 is a slot or key-way 61 and in the worm is also a slot and in these two slots is inserted a key 59, and when the cutters are adjusted horizontally with the shaft the key 59 travels in the slot 61. The outer edges of the cutters 52 and 54 are provided with cutting teeth whereby they engage the inner face of the aws of the frame.

Against the frame 16 is secured a shaft 62 provided with a worm 64.v Around this shaft is 'secured the power box 67 in which is located the turbine or power machinery (not shown). The preferable power is air and it is introduced by a flexible tube attached to the nozzle 66 of the box and adapted to rotate the shaft 62. The worm 64 meshes in with a gear 68. The back of the gear 68 is provided with a beveled gear 70 which meshes in with a beveled gear 72 secured to a shaft 74. This shaft extends down through or back of the plate 25 and through a collar 75 secured to the frame 16 and there is set on the lower part of the shaft 74 gears 76, 77 and 78 which mesh in with gears 80, 81 and 82 upon the screw 46. These gears 80, 81 and 82 are secured to a sleeve around the screw 46, terminating in a clutch 84 adapted to engage a similar clutch 85 upon the screw 46. The clutchis secured upon a screw shaft 46 bya setscrew86. Gears 76, 77, and 78, are speed changing gears, and are loosely mounted upon the shaft 74 and are independent of each other, the gear 76 meshes in with gear 80, gear 77 with 81 and 78 with 82, not all at the same time but according as it is desired to change the speed of the screw 46. The mode of bringing these different gears into action, is the usual mode of changing the speed by gears.

The cutters are operated by a shaft provided with a worm 92 which meshes in with the worm gear 57, upon the shaft 50. The

lower end of the shaft 90 is provided with a collar Q4 which rests upon a box 06 and below the box the shaft is provided with a gear 98 which meshes into a gear 100 and this into a gear 102 on the shaft 62. The worm 02, is splined upon the shaft Q0. The shaft has a longitudinal key-way on the back side, (not shown) the traveling length of the head 4 0 on the shaft. In the worm is fixed a key which slides in the key-way in the shaft. On both ends of the worm Q2 are bearings which run in boxes A on the head 40.

For the purpose of lowering the head at a rapid speed after it has finished the. milling, near the top of the aws there is placed at the lower end of the shaft 62 a gear 115 which is movable longitudinally on the shaft and when raised it engages the gear 81 on the screw 46 and as the shaft 62 is rotated at a great speed it will rotate the screw 46 rapidly and lower the head.

For the purpose of locking the shaft 56 and preventing any endwise movement there is attached a lock 105 shown in Figs. 6 and 7 which consists of a cam shaped shaft 106 threaded on the end 108 by which it is screwed into and held in the cutter head. One side 110 is flattened and in the outer end is a hole 111 in which is inserted an operating handle 112. In connection with the foregoing, is a plate 114 curved to fit the onter surface of the collar 55 with which the shaft 106 engages when turned. In this manner when the shaft 106 is turned in one direction. it presses the plate 114 upon the collar 55 and prevents it from being turned and thus holds the cutters rigidly in their' adjust ed position.

For the purpose of quickly and accurately adjusting the cutters 52 and 54 so that they will attack the jaws 4 and 5 of the frimw, there is secured to the raised portion or dovetail 21 of the frame 16 a gage 120 shown in Fig. 9. The gage is composed of two mem bers 122 and 124 and each provided with a bevel or hook 125 adapted to engage the dove-tail 21 of the frame 16. Each member is bent and forms the rectangularly arranged arms 126. rllhrough these arms passer-1 a bolt or set screw 128 and holds them together and the hooks 125 rigidly in engagement. with the dove-tail 21. The member 122 is further bent forming the arm 180. 'lhrough the. arm 130 is a gage screw 131.. There may be two of these gages 120 and 121.

It will be seen by this mode of constructing and associating the various parts of my device, that the cutters can be quickly and easily adjusted to attack and mill the. jaws ofthe frame at any angle desired, and they can be adjusted without disturbing the cutters or moving the frame from the frame of the engine.

The manner of operating my device is substantiall r as follows: The hangers 8 are ris'- I 1 and the machine is then hung on theframe 2 and clamps 1() secure the plate 6 tothe frame 2 then the frame 16 with the machinery thereon is adjusted by moving theframe to one side till the screws 131 on the gages `120 and 121 come in contact with the jaw: to be milled. ihen adjusted the bolts 20, 26 and 28 are tightened rigidly holding the frame 1 6 parallel with the jaw with one set of'cutters nearly in engagement with the face; of the The plate 25 is then adjusted and the clamps 33 are brought into engagement with the jaws and with the hangers 30, thus securing the xlowerA f end of vthe frame 16 to the jaws at the same angle as the jaw to be milled, then the collar 55 is operated which forces the shaft 50 with the cutter against the jaw `to be milled bythe cap 56 and the shoulder 60 upon thecollar 55 engaging with the shoulder 58 on the shaft 50,r and the operator grasps the handle 112 ef the lock and partially rotates it which engagesA the plate 114 and forces it down upon the collar 55 and prevents any further movement of the collar. As theshaft 74 is rotated the gears 76, 77 and 78 meshV ini-with the' gears 80, 81 and 82 and rotate the screw 46 whichraises and lowers the head 40 upon thescrew, and with it the cutters 52 and 54. The same rotation of the shaft 62 rotates the `gear102 which meshes in with the gear 100 and this with the gear 98 and rotates the shaft 90 and the worm 92 upon the shaft 90 engages with `the worm gear 57 upon the shaft 50 and rotates said shaft and with it the cutters 52 and 54. Iower then applied to the power box 67 through the nozzle 66 rotates the worm 64 upon the shaft 62 and also rotates the gear 70 and the gear 72 and with it the shaft 74. The clutch 85 is then brought into engagement withthe clutch 84 and is held by a set screw 86 and the rotation of the gear`57yro-` tates the shaft50 and with it the cutters.

When it is desired to mill the jaw 5 which sets at an angle to the frame, after having milled the jaw 4, the bolts 20, 26 and28 are loosened and the frame 16 withthe machinery thereon, is adjustedto the other side till the face of the cutter 52 is in a plane parallel with the face of the jaw toj'be milled, and the gages 120 and 121 are in contact with the jaw 5 and the frame parallel with the jaw 5; then the bolts 20, 26 and 28 andthe clamps 33 are tightened rigidly holding the frame with the cutters thereon in position to attack and mill the face of the angled jaw. The lock is then reversed, and the cutter 52 is adjusted the same vmanner as above described, and the collar is again locked. After one jaw has been milled `and the cutters are at the top, then they maybe lowered quickly by raising the gear 115 on the shaftv 62 till it comes into engagement with the gear 80 on thescrew 46 and as the shaft 62 rotates rapidly it will rotate the screw 46 rapidly and lower the head and with it the cutters at the same rate of speed. It will be observed, that in this mannerthe cutters may be adjustedto mill the aws at whatever angle the jaws may be set and also that the machine can be quickly and accurately adjusted and need not be removed from the frame `of the engine, at any time during the entire facing of both of the jaws.
